Check-in was done directly with Yi, who lives in the same building. The location is at walking distance from the airport train and subway stations. There are not many places to eat around the apartment, which was quite inconvenient. Yi was very nice and showed us a restaurant nearby. The apartment we booked wasn't available but we stayed in a similar one. At the end we changed to the booked apartment, which has a really nice view in the 28th floor. The apartment is small but comfortable. The bed is big but in the first apartment was really hard. Cleaning could be better.
